While the economy of scale would initially point to a merger being win-win, I personally have to vote no. Where I am at now:
- if I call the police for anything, they are out within a couple of minutes. This includes minor things such as -- oh I don't know -- a dog barking all night

, or if we want to hold an impromptu block party and need barriers.
- when it snows, my streets have been plowed at least twice and salted by the time the last flake falls
- if I want to make a comment or suggestion -- or resolve a problem -- I can call the mayor on the phone, or walk to an alderman's house, sit down, have a beer, and talk.
- building inspections are done by one guy, who's on a first name basis with just about everyone.
- just like the city, there are many parks within walking distance, as well as a pool/aquatic center within walking distance. Any issues or concerns? Just drop by the park director's office any time.
These types of reasons are exactly why many municipalities are reluctant to "merge" with the City -- or even with each other. It's not that anyone fears efficiency or doesn't understand economics. It's the simple fact that we have much more control over our little insignificant slices of the metro area and receive services such as these which we might see as lacking in other areas.
That being said, many cities are waking up to combining certain services such as fire dispatch, dog parks, swimming pools, and so forth. For example, Maplewood, Richmond Heights, Webster, and Shrewsbury have all saved tends of thousands of dollars by merging dispatch. Yet many
citizen-facing services are not going to merge for the very reasons I mentioned above -- the feeling of local control and what we feel are premium services versus those in other areas.
